Flourenst light's use gases to light up the bulb and can only be turned on or off and not be dimmed.

Fluorescant lights need to be driven by a reasonably pure sine wave. The normal knd of dimmer for incandescant bulbs distort the waveform too much. It could be done with the right bulb and dimmer. Selling special dimmers to people who do not know how to wire them correctly might kill someone and get you sued.

A dimmer reduces the voltage in a light circuit.
Fluorescent lights require a certain voltage to operate,if you reduce the voltage the ionization will stop.

The ballast controls the current through the lamp, in a manner to cause it to work properly. The dimmer will fight with the ballast for control -- and one or the other will lose. But you can get special dimmable ballasts if you want dimmable fluorescents; they are not cheap.

Conduction through a gas is a threshold phenomenon. If the voltage is too low, the gas will not ionized and there will be no conduction at all.

prolly cause they can't be dimmed. They need a certain wattage to maintain their light giving properties

because those type of bulbs run on gases and cannot dim gases
